hello every one i have a 210 gal tank and have 3-250 mh and 8-96 watt actinics . i was going to put 6 250s . i have a chiller but just didnt know if it was to much light .
3 400w would be much more efficient. Wouldnt be so hard on the wallet when time to order bulbs and it wouldnt run as hot. 400w will penetrate a deeper tank much better than 250 also. Just my 2 cents but 6 250s doenst seem very practical.
